Ipitingi ya aluminiyumu ntabwo ifite ibiranga firime ya pulasitike gusa, ariko kandi ku rugero runaka isimbuza ifu ya aluminium, igira uruhare mu kuzamura urwego rw’ibicuruzwa, kandi ugereranije n’igiciro gito. Kubwibyo, ikoreshwa cyane mugupakira ibisuguti nibiryo byokurya. Nyamara, mubikorwa byo gukora, hakunze kubaho ikibazo cyo guhererekanya aluminiyumu, biganisha ku kugabanuka kwingufu zo gukuramo firime ya firime, bigatuma igabanuka ryibikorwa, ndetse bikagira ingaruka zikomeye kumiterere yibipfunyika. Ni izihe mpamvu zo kwimura aluminiyumu? Ni iki gikwiye kwitabwaho mu mikorere ya tekinoroji?
Ni ukubera iki gutwikira aluminiyumu bikunda gusibanganywa?
Kugeza ubu, firime zikoreshwa cyane muri aluminiyumu ni firime ya CPP ya aluminium na firime ya PET ya aluminiyumu, hamwe na firime ijyanye na firime irimo OPP / CPP aluminium, PET / CPP aluminium, PET / PET aluminium, nibindi. Mubikorwa bifatika, ikibazo giteye ikibazo cyane ni PET igizwe na PET ya aluminium.
Impamvu nyamukuru yabyo ni uko nka substrate ya plaque ya aluminium, CPP na PET bifite itandukaniro rikomeye mumiterere ya tensile. PET ifite ubukana buhanitse, kandi imaze guhuzwa nibikoresho nabyo bifite ubukana bukomeye,mugihe cyo gukiza firime ifata, kuba hamwe bishobora guhita byangiza kwangirika kwa aluminiyumu, biganisha ku kwimuka kwa aluminiyumu. Mubyongeyeho, ingaruka zo kwinjiza zifata ubwazo nazo zigira ingaruka runaka kuri yo.
Icyitonderwa mugihe cyo guhuza ibikorwa
Mu mikorere yuburyo bukomatanyije, hagomba kwitonderwa ibintu bikurikira:
(1) Hitamo ibifatika bikwiye.Mugihe utwikiriye aluminiyumu, witondere kudakoresha ibifatika bifite ubukonje buke, kuko ibifunga bike byijimye bifite uburemere buke bwa molekile nimbaraga nke za intermolecular, bikavamo ibikorwa bya molekile bikomeye kandi bikunda kwangiza kwizirika kwabo kuri substrate binyuze muri aluminiyumu ya co. firime.
(2) Kongera ubworoherane bwa firime ifata.Uburyo bwihariye ni ukugabanya ingano yumuti ukiza mugihe utegura ibifatika bikora, kugirango ugabanye urugero rwimikorere ihuza imiyoboro nyamukuru nuwashinzwe gukiza, bityo bigabanye ubukana bwa firime ifata kandi bikomeza guhinduka no kwaguka, bikaba bifasha kugenzura ihererekanyabubasha rya aluminium.
(3) Ingano ya kole ikoreshwa igomba kuba ikwiye.Niba ingano yo gufatira hamwe ikoreshwa ari nto cyane, nta gushidikanya ko izavamo umuvuduko muke hamwe no gukuramo byoroshye; Ariko niba ingano yifatizo ikoreshwa ari nini cyane, ntabwo ari byiza. Ubwa mbere, ntabwo ari ubukungu. Icya kabiri, ubwinshi bwamavuta akoreshwa hamwe nigihe kirekire cyo gukira bigira ingaruka zikomeye zo kwinjira kumurongo wa aluminium. Umubare wuzuye wa kole ugomba guhitamo.
(4) Kugenzura impagarara neza. Iyo udashaka gukuramo aluminiyumu,impagarara zigomba kugenzurwa neza kandi ntabwo ziri hejuru cyane. Impamvu nuko igipande cya aluminiyumu kizarambura munsi yuburakari, bikavamo guhinduka kwa elastique. Igikoresho cya aluminiyumu nacyo cyoroshye kurekura kandi gufatira hamwe biragabanuka.
(5) Umuvuduko wo gukura.Ihame, ubushyuhe bwo gukiza bugomba kongerwa kugirango byihute gukira, kugirango bishoboze molekile zifatika gukomera vuba no kugabanya ingaruka zangirika.
Impamvu nyamukuru zo kwimura aluminium
(1) Impamvu zitera guhangayika imbere muri kole
Mugihe cy'ubushyuhe bwo hejuru bwo gukiza ibice bibiri bifatanye, imihangayiko y'imbere iterwa no guhuza byihuse hagati yumukozi mukuru nuwakize bitera kwimura aluminiyumu. Iyi mpamvu irashobora kugaragazwa hakoreshejwe igeragezwa ryoroshye: niba igipande cya aluminiyumu idashyizwe mu cyumba cyo gukira kandi igakira ku bushyuhe bw’icyumba (bifata iminsi myinshi kugira ngo ikire neza, idafite akamaro gakomeye ko gukora, ni igeragezwa gusa), cyangwa irakira ku cyumba cy'ubushyuhe bw'amasaha menshi mbere yo kwinjira mucyumba cyo gukiza, ibintu byo kohereza aluminium bizagabanuka cyane cyangwa bivaho.
Twabonye ko gukoresha 50% yibintu bifatika bifatanye na firime ya aluminiyumu, nubwo hamwe nibintu bike bifatika, byavamo imyitwarire myiza yo kwimura. Ibi ni ukubera neza ko imiterere y'urusobekerane rwakozwe nibintu bike bifatika bifatika mugihe cyo guhuza ibintu ntabwo ari byinshi nkuko imiterere y'urusobekerane rwakozwe n'ibikoresho bifatika bifatika, kandi imihangayiko y'imbere yatanzwe ntabwo ari imwe, idahagije kugirango yuzuye kandi imwe. kora kuri aluminiyumu, bityo kugabanya cyangwa gukuraho ibintu byo kwimura aluminium.
Usibye itandukaniro rito hagati yumukozi wingenzi nuwifata bisanzwe, imiti ikiza kumashanyarazi ya aluminiyumu muri rusange ntabwo ari munsi yumuti usanzwe. Hariho kandi intego yo kugabanya cyangwa kugabanya imihangayiko yimbere iterwa no gufatana hamwe mugihe cyo gukira, kugirango ugabanye ihererekanyabubasha rya aluminiyumu. Ku giti cyanjye rero, nizera ko uburyo bwo "gukoresha ubushyuhe bwihuse bwo gukomera kugirango bikemure ihererekanyabubasha rya aluminiyumu" ntabwo bishoboka, ahubwo bivuguruza. Ababikora benshi ubu bakoresha ibifatika bishingiye kumazi mugihe bahujwe na firime ya aluminiyumu, ishobora kandi kugaragazwa nuburyo buranga imiterere y’amazi.
(2) Impamvu zo kurambura deformasiyo ya firime yoroheje
Ikindi kintu kigaragara cyo kwimura aluminiyumu kiboneka mubisanzwe mubice bitatu, cyane cyane mubikorwa bya PET / VMPET / PE. Mubisanzwe, tubanza guhuriza hamwe PET / VMPET. Iyo ikomatanyije muriki gice, aluminiyumu ntisanzwe yimurwa. Ipfunyika ya aluminiyumu ikorwa gusa nyuma yicyiciro cya gatatu cya PE igizwe. Binyuze mu bushakashatsi, twasanze mugihe cyo gukuramo ibice bitatu bigize icyitegererezo, niba umubare munini wimpagarara zashyizwe kurugero (ni ukuvuga gukomera muburyo bw'icyitegererezo), igipande cya aluminium ntikizimurwa. Iyo impagarara zimaze kuvaho, igipande cya aluminiyumu kizahita cyimurwa. Ibi byerekana ko kugabanuka kwa firime ya PE bitanga ingaruka zisa nihungabana ryimbere ryatewe mugihe cyo gukiza. Kubwibyo, mugihe ibicuruzwa bihujwe hamwe nuburyo butatu, imiterere ihindagurika ya firime ya PE igomba kugabanuka cyane bishoboka kugirango igabanye cyangwa ikureho ibintu byo kohereza aluminium.
Impamvu nyamukuru yo kwimura aluminiyumu iracyari firime ya firime, nimpamvu ya kabiri ni ifatizo. Muri icyo gihe, ibyubatswe bya aluminiyumu bitinya cyane amazi, kabone niyo igitonyanga cyamazi cyinjira mubice bigize firime ya aluminiyumu, bizatera gusenya bikomeye.
